The number of tiller of rice genotype was investigated during the tilleringperiod, and calculate the relative tillering rate.
分蘖期调查水稻基因型的分蘖数，计算其相对分蘖率。
2
Growth rate reach peak from heading stage to ripe period for above-ground biomass, from tilleringperiod to (jointing) stage for under-ground biomass.
地上生物量增长最快在抽穗到成熟期，地下生物量增长最快在分蘖期到拔节期。

The results show a great variation in methane emission during the rice growing season, and the peak values appear during tilleringperiod and fruiting period.
